Invisible password reset protocol

Techniques are disclosed herein for facilitating invisible password reset protocols. More specifically, the techniques described herein eliminate the need for end users to have to periodically change their authentication information (e.g., password information). The mechanisms facilitate automated and invisible modification to a password without active participation by the end user. The mechanisms are made possible through the use of a credential-free or zero password login (ZPL) system. Among other benefits, the automation techniques discussed herein frequently change passwords and thus, reduce the chances that passwords are stolen and/or otherwise misused. As discussed herein, the credential-free or zero password login (ZPL) system also remembers and/or otherwise automatically provides users with authentication information (e.g., credentials) for a registered resource at the time of access time.
